Convert from Decimal Notation to Scientific Notation

DIA [1.3K]

Answer:

Hence, 0.00000103 can be expressed as $1.03 \times 10^{-6}$ .

Step-by-step explanation:

- Given 0.00000103

- Move the decimal point so that the factor is greater than or equal to 1 but less than 10 .

- Then count n and write no. as a product with a power of 10 .

Step 1 of 1

Consider 0.00000103,

1.03

Decimal has moved 6 places to right.

The power will be negative as the original no. is less than 1 .

$\begin{array}{r}1.03 \times 10^{-6} \\0.00000103=1.03 \times 10^{-6}\end{array}$

How might this number be shown on a calculator?<br> 5.31x1037 (37 is above 10)<br> [?]e[ ]

Arisa [49]

Answer:

$5.31E37$

Step-by-step explanation:

Given

$5.31 * 10^{37}$

Required

How it'd be displayed on a calculator

Standard calculators, today are built to always convert huge numbers or extremely small number to scientific notations;

This was done to allow the calculator fit each values on its screen

$5.31 * 10^{37}$ is such a big number that it'll require the calculator to display it using scientific notations;

So, basically we have to convert $5.31 * 10^{37}$ to scientific notaton;

This is achieved by replacing $*10^{37}$ with $E37$

So, $5.31 * 10^{37}$ is equivalent to $5.31E37$

POSSIBLE POINTS. 1

erastova [34]

Answer:

Step-by-step explanation:

a^2 + b^2 = c^2

where

a and b are the legs

and

c is the hypotenuse

the problem gives the "legs" because the LONGEST leg is always the hypotenuse.

a^2 + b^2 = c^2

1071^2 + 1840^2 = c^2

1147041 + 3385600 = c^2

4532641 = c^2
